摘要
Provided is a method of joining compound materials such as ceramics. The method is a combination of diffusion bonding and reaction bonding, which is called reaction diffusion bonding (RDB). The method includes: grinding, lapping, or polishing entire or portions of surfaces to be joined of two or more pieces of a compound material; forming a thin film of a joining agent on one or more of the ground, lapped, or polished surfaces by one of inserting, spreading, depositing, plating, and coating, the joining agent being able to transform into the compound material by being incorporated into the compound material or by forming a solid solution with the compound material upon heat treating; and forming a directly bonded interface without a second phase by heat treating the pieces of the compound material with the to-be-joined surfaces on which the joining agent film is formed arranged to face each other, wherein the joining agent thin film is composed of a material selected from the group consisting of metals, metal organics, and metal compounds.
